Cows automatically point to the north because they have their own in-built compasses aligning them with the Earth’s magnetic field, scientists have discovered.

Researchers discovered that cattle have a good sense of direction and tend to point in a northerly direction.

It has long been observed that cows appear to have a talent for weather forecasting and are able to predict when rain is on the way, but until now their navigational abilities have been largely ignored.

Their innate ability to find north is believed to be a relic from the days when their wild ancestors needed an accurate sense of direction to migrate across the plains of Africa, Asia and Europe.

Dr Sabine Begall and colleagues from the University of Duisburg-Essen looked at thousands of images of cattle on Google Earth in Britain, Ireland, India and the USA. They also studied 3,000 deer in the Czech Republic. The deer tended to face north when resting or grazing.

A wild dolphin is apparently teaching other members of her group to walk on their tails, a behaviour usually seen only after training in captivity.

The tail-walking group lives along the south Australian coast near Adelaide.

One of them spent a short time after illness in a dolphinarium 20 years ago and may have picked up the trick there.

Scientists studying the group say tail-walk tuition has not been seen before, and suggest the habit may emerge as a form of “culture” among this group.
